Glass wool and rock wool are widely used in the construction industry, but there are still some customers who are not familiar with the difference between glass wool and rock wool. They often think that glass wool and rock wool are the same product, but in fact, glass wool and rock wool are different. So how can we distinguish them? Below, let's elaborate on 5 different points by the editor of Shengyuan.

一、原材料和生產工藝不同

1、 Different raw materials and production processes

玻璃棉原材料是玻璃為主，再按照適合的比例配加其它各種輔料混合后送入玻璃熔爐中充分融化再經多道工序，完成固化過程、產品定型、定型后經切割便成了預定產品，再進行包裝。

The raw material of glass wool is mainly glass, which is then mixed with various other auxiliary materials in a suitable proportion and sent to a glass furnace for full melting. After multiple processes, the curing process, product shaping, and cutting are completed to form the predetermined product, which is then packaged.

巖棉是由玄武石為主要原料，經高溫熔融，由離心設備制成無機纖維后再加入特質粘結劑和防塵油經擺動帶鋪氈并通過一些設備改變纖維排列結構，后經固化定型而制成的新型輕質保溫材料。

Rock wool is a new type of lightweight insulation material made from basalt as the main raw material, which is melted at high temperature and made into inorganic fibers by centrifugal equipment. It is then added with special binders and dustproof oil, laid on a swing belt, and the fiber arrangement structure is changed through some equipment. Finally, it is solidified and shaped.

二、產品性能不同

2、 Different product performance

玻璃棉比巖棉容量低、渣球含量少、導熱系數低、使用年限長、纖維韌性大。

Glass wool has lower capacity, less slag ball content, lower thermal conductivity, longer service life, and greater fiber toughness than rock wool.

二、產品用途不同

2、 Different product uses

玻璃棉一般用于低于200℃的保溫部位，多用于一般建筑物貨低溫管道的保溫，巖棉一般用于溫度在500℃的保溫部位，多用于高溫熱力管道和電力設備的保溫。

Glass wool is generally used for insulation parts below 200 ℃, and is mostly used for insulation of general buildings and low-temperature pipelines. Rock wool is generally used for insulation parts at a temperature of 500 ℃, and is often used for insulation of high-temperature thermal pipelines and power equipment.

三、產品容量不同

3、 Different product capacities

玻璃棉容重為10kg/m3-64kg/m3，巖棉容重為40kg/m3-200kg/m3，因此巖棉的機械強度大于玻璃棉，所以巖棉成為了現代外墻壁掛保溫防火的先選材料。

The unit weight of glass wool is 10kg/m3-64kg/m3, and the unit weight of rock wool is 40kg/m3-200kg/m3. Therefore, the mechanical strength of rock wool is greater than that of glass wool, making rock wool the first choice material for modern exterior wall insulation and fire prevention.

二、憎水性能不同

2、 Different hydrophobic properties

憎水性能也就是耐水滲透的一個性能指標。玻璃棉不會因為浸水和淋雨而破裂，被水浸泡后易行干燥，性能穩定。巖棉被水浸泡后即會軟塌，性能喪失很多。

Hydrophobicity is also a performance indicator of water permeability resistance. Glass wool will not break due to immersion in water or rain, and it is easy to dry after being soaked in water, with stable performance. Rock wool will collapse and lose a lot of performance after being soaked in water.
